Storage Redundancy (1 / 16): ViralTrendz Inc. operates a popular platform for sharing short videos (think TikTok on a dose of creative steroids) and stores users' videos in Azure with Geo-Redundant Storage with Read Access (GRS-RA). Suddenly, day-to-day operations are disturbed by a full-blown zombie outbreak in the region of their primary storage. What will happen to users who rush to the app to save their beloved dance-offs and lip-sync masterpieces in this scenario?
Answer:
With GRS-RA, data is replicated to a secondary region and users have read access to the replicated data in the secondary region during normal operations. However, in the event of an outage at the primary region, a manual failover to the secondary region needs to be performed by the company. Until this failover is performed, users might experience a short period of downtime.
"Users will not be able to access their videos until the zombie outbreak is resolved." is incorrect because users will eventually be able to access their videos after a manual failover is performed.
"Users will be able to access their videos as usual because the data has been automatically failed over to the secondary region." is incorrect because automatic failover does not occur with GRS-RA; a manual failover is required.
"Users will not be able to access their videos because the secondary region only allows read access during normal operations." is incorrect because while the secondary region does provide read access during normal operations, it also serves as the failover region where both read and write operations can be performed after a manual failover.
"Choosing GRS-RA was a mistake" is incorrect because other servers in the same zone might get compromised as well.
